Long after the fall of the Roman Empire, in England in the year 1588, two unicorns appeared on the hunting grounds of Hampton Court. Star Swirl and Clover the Clever meet with the Lioness of England: Queen Elizabeth Tudor.
Twilight changes Star Swirl's time spell to travel back to the past once more. She ends up in the Pre-Equestrian era and unwittingly saves two fillies in the process. Little did she know what teaching them magic can do for the fate of Equestria.
